The present work aims to prepare biocomposites blend based on linear low density polyethylene/ starch without using harmful chemicals to improve the adhesion between two phases. Also, the efficiency of essential oils as green plasticizers and natural antimicrobial agents were evaluated.

Barrier properties and biodegradation behavior of linear low density polyethylene/starch (LLDPE/starch) blends plasticized with different essential oils including moringa oleifera and castor oils wereassessed as a comparison with traditional plasticizer such as glycerol. Biodegradation behavior forLLDPE/starch blends was monitored by soil burial test. The composted samples were recovered then washed followed by drying, and weighting samples after 30, 60, and 90 days to assess the change in weight loss. Also, mechanical properties including retention values of tensile strength and elongation at break were measured before and after composting. Furthermore, scanning electron microscope (SEM) was used to evaluate the change in the morphology of the polymeric blends. In addition to, the antimicrobial activity of plasticized LLDPE/starch blends films was evaluated using a standard plate counting technique.

The results illustrate that the water vapor transition rate increases from 2.5 g m⁻² 24 h⁻¹ for LLDPE/5starch to 4.21 g m⁻² 24 h⁻¹ and 4.43 g m⁻² 24 h⁻¹ for castor and moringa oleifera respectively. Also, the retained tensile strength values of all blends decrease gradually with increasing composting period. Unplasticized LLDPE/5starch showed highest tensile strength retention of 91.6% compared to the other blends that were 89.61, 88.49 and 86.91 for the plasticized LLDPE/5starch with glycerol, castor and M. oleifera oils respectively. As well as, the presence of essential oils in LLDPE/ starch blends increase the inhibition growth of escherichia coli, candida albicans and staphylococcus aureus.

The objective of this work is to develop cost-effective and environmentally-friendly methods for preparing biodegradable polymers suitable for packaging applications.

The purpose of this paper is to develop an analytical account on the contemporary architecture of Cairo with emphasis on the past three decades, from the early 1990s to the present. The paper critically analyses narratives of the plurality of “isms”, within architectural vocabulary and discourse, that resulted from the contextual particularities that shaped it.

Three lines of inquiry are envisioned as overarching aspects of architecture: the chronological, the interventional and the representational. These discussions are underpinned by the discourse of decolonialisation and cosmopolitanism, posited sequentially by Frantz Fanon in The Wretched of the Earth (1961), and Ulrich Beck in The Cosmopolitan Vision (2004). The analysis expands to interrogate these two notions as prelude for reflecting on representations of selected projects: The Smart Village (2001); the Great Egyptian Museum (2002), Al-Azhar Park (2005), American University in Cairo New Campus (2008/2009), and the New Administrative Capital (2018).

The investigation on the interventional and the representational levels via aspects of discursivity and contradictions highlights that decolonisation and cosmopolitanism are two inseparable facets in the architectural practice in Egypt’s 21st century. These indivisible notions are based on idiosyncratic core to human experience, which emerged from concurrent overturning historical and secular everyday life striving to suppress ideological supremacy.

Further detailed examples can be developed to offer discerning elucidations relevant to both notions of cosmopolitanism and decolonialisation.

The paper offers novel theoretical analysis of Cairo’s most recent architecture. The reflection on the notions of decolonialisation and cosmopolitanism is a timely example of the complex cultural encounters that have shaped the Egyptian architecture, given the recent interventions by the “Modern State” that legitimised such notions.

Egypt has set plans to transform into a green economy which requires major reforms in the waste sector as one of the most vital sectors crucial for this transformation. This study aims at inspecting the current status of the Egyptian waste sector to highlight the major policy reforms needed. Furthermore, it assesses the economic viability of establishing waste-to-energy (WtE) projects under the current regulations that govern the sector.

The study employed an inductive analytical approach to scrutinize the institutional and regulatory framework of the waste and WtE sectors. Furthermore, a novel techno-economic analysis was conducted to assess the profitability of a WtE plant that employs moving grate incineration technology.

The analysis of the waste sector revealed its deteriorating state and the dire need for immediate restructuring through more stringent regulations to establish an integrated waste management system (IWMS) that incorporates WtE technologies as well as a number of corrective actions that would help enhance the sector. Additionally, the techno-economic analysis revealed the need to amend the current WtE regulation to comprise a gate fee as an indispensable revenue stream for WtE projects.

This study is one of a few studies that uses a new technique of analysis to explore the potential role that WtE projects can play in Egypt as a part of an IWMS that aims at transforming the waste sector into a resource sector while providing a renewable and sustainable source of energy.

The purpose of this paper is to analyze the postgraduate disciplinary trends in architecture in Jordan. It highlights current research topics in master theses of architecture programs, to enhance the selection of postgraduate thesis topics that are more responsive and adaptive to the raised research demands of communities and the profession.

The paper analyzed 254 master's theses published from 2009 to 2019 in three Jordanian universities. The paper employed a descriptive and content analysis for theses' titles and abstracts.

The principal results identify unique geographical, temporal and disciplinary trends in the mapped theses. The findings illustrate an interest in disciplines of design studies, building technology, housing and community and urban design among postgraduate students. The findings also highlight a centralization of theses' number and geographical location within Amman governorate. Many theses also focused on residential spaces as a scale of analysis.

The proposed suggestions include collaborative efforts and practical mechanisms by higher education institutions, practitioners and decision-makers for advancing rigorous, diverse and relevant research topics in postgraduate theses.

The paper provides a comprehensive mapping of the topics of postgraduate theses in the field of architecture. It highlights how they have evolved or have been influenced by community needs. It also draws attention toward specific disciplines that have been the focus of major architectural programs in Jordan. Finally, it highlights the coexistence of interdisciplinarity within the field of architecture.
